application filed lZlanuary 211i, wit.

To all whom it may concern:

Be it known that l, Grenen WAL'rnnn, citizen of the lUnitedStatearesiding at Dayton, in the county of Montgomery and State oftOlhio, have invented certain new and useful yImprovements in Castll/lletal eels and il do declare clear, andV exact description of theinvention, such as will enable others skilled in the art to which itappertains tomake and use the same, reference being had to theaccompanying drawings, and to the letters and figures which form a partof this specification.4

Illhis invention relates to certain improvements in vehicle wheels suchasare specially designed for motor trucks. rlFhe object of the presentinvention is to provide a wheel of increased strength and durabilityatthev rim without materially increasing the vweight thereof. ln such aconstruction the spokes may be solid, or in other words, the wheel maybebuilt up or the spokes may be hollow and integrally unite to the rim.

ith the foregoing object in view, the invention will be moreparticularly described in connection with the accompanyin drawings, ofwhich Figure 1 is a side e evation of my improved cast thereof brokenaway on the line l-l of Fig. 2 to facilitate the illustration. Fig. 2 isa sectional view on the line 2--2 of Fig. 1.

Referring in more vparticular terms, l designates the hub, 2 the spokes,and 3 the rim, all of which are integrally united by being made in asingle steel casting; rllhe spokes 2 are hollow as is also the hub 1norder that a desirable degree of lightness of the structure shall beobtained and at the same time strength shall .likewise be obtained intpecication of Lettere Fatent.

the structure. .ds before stated the spokes may be solid if by so makingthem the weight ofthe wheel is not perceptibly rihe said spokes wherethey leave the hub l entend in broadly sweeping curves il, and also theouter endsof ,said spokes extend to the rim 3 in broadly sweeping curves5. 'llhe said spokes are provided with openings 6 through which thecores used in making the casting may be removed from the spokes in aconvenient manner. feature which involves the present invention, the rimof the wheel, whetherit be integrally united Ato the spokes or whetherthe spokes are hollow, is corrugated annularly through out thecircumference thereof to increase the strength of said rim. Thesecorrugations are formed by a number of annular depressions 8which'provide a'number of peripheral corrugations 7 throughout thecircumference of the wheel. lin the drawings three such annulardepressions are shown and four annular corrugated surfaces, but it willbe to the width of the rim or in accordance with the size of thedepressions. llt is tobe understood that around the rim so corrugated anelastic tire is placed. This, however, is no part of the presentinvention `and its illustration has therefore been omitted.

Having described my invention,

A metal wheel, the hub, spokes and rim. of which consist of one integralcasting and the hub and spokes thereof being hollow, the rim being of asingle thickness of metal and provided throughout its circumference,substantially as described.,
